4. A spring cushion. assembly including a seat cushion and a back cushion associated therewith, with the lower end ofthe back cushion overhanging the rear vend of the seat cushion and closely adjacent thereto, the back cushion comprising a rear frame, top and bottom front frame memposed loops therein of substantial length extending transversely of the length of the unit and having reaches between the loops disposed lengthwise of the unit in side by side relation and a helical tie member threaded upon said reaches, said units having rearwardly and upwardly projecting supporting arms at their lower ends mounted at their upper ends on the rear frame, the lower ends of said spring units being secured to the bottom front frame member, and upholstery arranged over and supported by said spring units whereby simultaneous compressive stresses on the seat and back cushions act to maintain the lower end of the back cushion in adjacent relation to the compressed seat cushion.

5. A back cushion comprising a rear frame, top and bottom front frame members, the top member being spring supported, and a plurality of vertically disposed forwardly bowed spring units each comprising strands of spring wire having longitudinally spaced oppositely disposed loops therein of substantial length extending transversely of the length of the unit and having reaches between the loops disposed lengthwise of the unit in side by side relation and a helical tie member threaded upon said reaches, said units having rearwardly and upwardly projecting supporting arms at their lower ends mounted at their upper ends on the rear frame, the lower ends of said spring units being secured to the bottom front frame member.

6.
